has anyone ever used the Opteka lenes, are they any good?
cuz, im looking at getting the 100-300mm lens and I wanna know before I get it if its worth the $?

thanks,

I have never heard of that lens before... Maybe someone else has but I certainly have not... Some advice that gets repeated a lot not only in this forum but other profession review sites is this, "You get what you pay for..." Good luck

thats what im afraid of....
thats why im here to see whats good and what NOT.....

The only place I've seen selling the Opteka lenses is eBay. Which makes me believe that if they were any good then places like B&H would be selling them.

If can get the lens cheap, then there has to be a reason.

I recomend looking for inexpensive Canon lenses on eBay. A lot of people are selling their old Canon glass to purchase something with the new Image Stabilizer or are upgrading to the red ringed L series.

I found the best way to purchase a used 50mm 1.8 mark 1 lens on eBay was not to buy it alone, but with an included film camera. The price was $50 less that way.

No matter what and where you buy it, always remember Caveat Emptor (latin for "Let the buyer beware")

Hello, I have been in search of a good price to performance ratio for lenses. I have found a number of tempting deals usually from 3rd party manufacturers... from everything I've been reading there are very real advantages to buying lenses from the same vendor as your dSLR body... specifically because companies like Tokina, Sigma, etc have to reverse engineer the protocol the camera uses to control the lens, this is why a lens you purchase may not work with a future body that may use the same lens mount... My advice is to wait and save up the $$$s to buy a Canon lens for your Canon camera. For the budget concious sites like www.keh.com and others list used lenses. I know I'd rather have a lightly used canon lens on my 20D than a brand new lens from a 3rd party manufacturer. That being said there are always exceptions to the rule... best of luck.

Personally I have had excellent experiences with the Canon EF 18-135mm IS lens and Sigma 18-125mm lens. The Sigma is 40% less in cost than the Canon lens.

Those are accessory lenses for the S2 IS - totally different from the SLR lenses which are being discussed here ...

I've talked to several folks with sigma and tamron lenses for their 20D bodies, universal agreement is that they focus slower and sometimes "hunt" for focus an awful lot more than real canon lenses. Optically there are great third party products but until Canon is forced to share lens protocols (and I really don't understand why there hasn't been a law suit yet) this problem won't get any better. I like my 20D but I'm waiting for the Pentax *Ist (not ist D) to get reasonable so I can use all my old k-mount glass that's been sitting in a camera bag for years and is better quality than most of the canon consumer level glass that costs a lot more than my old lenses did.

There is nothing wrong with sigma lenses, the consumer ones focus no slower than the canon consumer lenses. If the sigma lens has HSM or canon lens has USM, they will focus just as fast.

I was just guessing about the quality (digital camera mode doesn't matter) of the opteka lenses and specifyng that you can find them on amazon.com too and there is an opteka site...

(and I really don't understand why there hasn't been a law suit yet).

On what grounds?

[suemccartin]

On what grounds?

Probably the same grounds used against microsoft for trying to fix things so only they can sell a product that works 100% properly with their product......................

Silly stuff. Tamron does not have the weird problems some Sigmas seem to have, and Tamron and Tokina lenses are fine with Canon cameras as they are with Nikon cameras and Pentax cameras. The problem seems to be that Sigma does not want to license from Canon how the AF system works between lens and camera. My Tamron 90mm macro can hunt sometimes, and is slow to focus with a noisy motor, and it will be the same on a Nikon mount and Pentax mount. It has NOTHING to do with Canon (and it is a great lens regardless).
The focus speed and if it will overshoot focus has to do with the AF motor and its electronics, and the construction of the lens itself.

Lets sue Sony and Philips for licensing their CD format, lets sue everyone and everything who does not just open up every detail of how their products are developed???

Microsoft uses their monopoly position in the OS market to gain the upper hand with file formats and data formats that are not necessarily better, and that is why Microsoft at times is targetted by justice departments and european commissions, because the playing field is not level for all players. I can not recall Microsoft being sued for requiring other companies to license things from them though. Sometimes they get sued for copying someones idea or for patent related issues. But that is hardly the same.

You're kidding right? Canon makes cameras and accessory lenses to go with said cameras - Who said they have to let their competitors in on their IP?

And you reckon it would be fair to sue them for this?

No wonder there are so many rich lawyers in America with that sort of attitude.
